I have an 8700 blackberry and I can browse the internet with the browser that already comes with OS 4.2, even if I don't configure the APN.
My carrier is Movistar Argentina.

However I have a java application (a Midlet, I also have it's source code) that needs to access the internet (some webservice). If I configure the APN with internet.gprs.unifon.com.ar user wap/ pass wap the midlet seems to work, but if I don't configure any APN the midlet doen't connect to the webservice.

But accessing the internet through the APN isn't included in the fixed mensual cost for internet from the blackberry, so I would like to know if there is a way to make the Midlet access the internet through the same channel than the browser (I think it's the carriers BIS), instead of the APN.
